as evidence for what Christianity in the US is like is intentionally misleading
If I was trying to claim that is that standard view, then it would be misleading. Since I was actually claiming that there are a wide variety of beliefs among Christians, some even aligning with your values, it is pretty spot on representation. Treating them all the same is prejudicial behavior.
A fair-minded person would give an individual a chance to act like an asshole before treating them like trash.
It sounds an awful like you are saying, “Well yeah, we are bigots, but we are bigots because they deserve it!”
Am I misunderstanding you?
